Living Green - Episode 67 - Extracting Heat From The Earth

Ground source heat pumps are devices that transfer heat from the earth to warm building interiors, functioning similarly to refrigerators. They are more efficient than traditional heating methods, providing 3 to 4 units of heat for every unit of energy used. This technology is applicable for space heating and hot water in residential, commercial, and industrial buildings.

What is the primary function of ground source heat pumps?

• To cool the interior of a building

• To transfer heat from the earth to the building

• To generate electricity

• To store heat in the earth

How do heat pumps differ from conventional electric heating?

• They are only used for cooling

• They provide more heat for each unit of energy used

• They are less efficient than electric heating

• They use more energy to produce less heat

For every unit of energy used by a heat pump, how many units of heat are typically supplied?

• 4 to 5 units

• 3 to 4 units

• 2 to 3 units

• 1 to 2 units

In which types of buildings can heat pump technology be applied?

• Only residential buildings

• Only industrial buildings

• Only commercial buildings

• Residential, commercial, and industrial buildings

What can heat pump technology provide besides space heating?

• Electricity generation

• Cooling solutions

• Domestic hot water

• Air purification
